Be it known that I, Oscar: KATZENBERGER, a citizen of the United States, and a resident of'Chica'go, in the county of Cook and State ofIllinois, have invented a new and Improved Pivot Spring-Hinge, ofwhich the following is afull, clear, and exact descrip'- tion." r

This invention{ relates to spring hinges and has for an object-the provision" of an usedfor doublefswinging doors located at various places and for various purposes, without injuring the door or the support andwith assurance that'the door will act in 11 A further object of the invention is to provide aspringhinge for a door which does not require expertness' in mounting, while at the same time presenting a sure ad justnient for producing aiproper alincment.

.A still further object of the invention is to provide a box or othersupport associated adjustably connected to one; of said pivots movement provided by the pivots while caused to return to'a given position by the springmechanism. II

In the accompanying drawings Figure 1 is a top plan view of a hinge" embodying the' invention, the same heingf shown secured to a door and an adjacent support. f I g I an Fig. 2 is a side view: of the structure shown inFig.'1.

Preferably an" win when is into t e socket: 2 5- is noved away' will be brought idly fixed in place when the parts are properly adjusted. In order to transfer the strain of spring 31 from the plates 26 and 27 to the door 2 casing 22 is provided with a lug 34 (Figs. 4: and 5) said lug acting on the shoulders 35 and 36 of plates 26 and 27' as shown particularly in Figs. 4 and 5. In this construction and arrangement, whenever the casing 22 is rotated either the top plate 26 will be moved or the bottom plate 27 and will consequently bring the spring under greater tension. The casing 22 is secured to the door 2 by any suitable means, as for instance by the extension 37 which is preferabl thoiigh it may be made separately and rigidly secured thereto. The extension 37 isv rigidly secured to the door by any suitable means, as for instance by screws '38. A bottom covering member 39 is secured to casing 22, said covering member causing'the casing 22 to be substantially dust-proof, while at the same time acting as a support for the 'lower plate 36. lVhen the door 2 is opened in one direction one of the platesconnected with the spring 31 presses againstthe rib or bar 34 and when the door swings in the opposite direction the other plate connected with the spring presses in the opposite direction on rib or bar 34. When it is desired to. have the door 2 in direct alinement with the support 1 the lug 23 is arranged opposite lug 34: as shown in Fig. 5, whereby the spring continually tends to bring the door back to.

a proper alinement. In case it is desired that the door should stop at any point on either side of the position shown in Fig. 5, screw 32 is loosened and the door raised slightly so that the pin 19 may be rotated to any desired extent, after which the screw 32 is again tightened and the device is in position for properly returning thedoor to the new position when moved therefrom.

Boxes 7 and 15 have been shown and'described. because the hinge has been shown connected to a lavatory partition, but it will be evident that other formsof supporting connections may be provided without departing from the spirit of the invention, whenever desired, as for instance office gates. These boxes are desirable for marble slabs and also the'support 40 is usually positioned so as to prevent aniordinary box or connection to be provided. 'It will be noted that the box 15 as well as the box 7 is provided with a neck or extending portion 41 which affords the support 40, while-allowing the clamping bolts 42 to be placed the desired distance back from the'edge of the support 1.

What I claim is: r

1. A pivot spring hinge comprising a piv otal pin having a tapering lower end, a connecting member for connecting the pivotal 1 pin with a support, said connecting member having a tapering aperture for receiving made integral with the casing 22' ,a given position and. moved back each end, each of said plates having shoulders facing in opposite directions, the shoulv der on one plate engaging one side of said lug and the shoulder on the other plate engaging the opposite side of said lug, a spring surrounding said pin with one end projecting into one of said plates and the opposite end projecting into the opposite p1ate,a cas- 7 ing adapted to be connected toa door, a projection extending from said casing, and means on each of said plates overlapping said projection, said overlapping means ens gaging said projection on opposite sides whereby the said door' is normally held in by said springwhen movedthereffroin. Y

2. A pivot hinge comprising a supporting structure, adapted to be connected witha door, said supporting structure having a pivot pin and a supporting box for engaging a support, said box having an arm formed with an opening for receiving saidpin, a face plate for engaging fiatwise said support and a side plate integral therewith, a pair of lugs extending I from said face plate, an adjustable side plate, screw members extending through said adjustable side plate into said lugs, and a bolt arranged on the opposite edge of said side plates fron said lugs and extended through the side/plates.

3. A pivot spring hinge comprising ap i v otal pin having a lug extending longitudi nally thereof and falling short of the ends, a stationary support connected with one end of said pin, a casing having a socketfitting over the opposite end of said pin, said casing being adapted ing web extending from one end of said casing to the other parallel with said lug, a pair of plates surrounding said pin having projections overlapping said web engaging OP? posite sides thereof andshoulders engaging opposite sides of the lug on said pin, and a coiled spring having one end secured toone of said plates and the opposite end secured to the other of said plates. r

4. A pivot hinge of the. character de pivot pin, a stationary support therefor be. ing rigidly secured thereto,a casing for said:

lower pin engaging said door for supporting to support'a door, a project the same, said casing resting on said last' casing, a pair of oppositely positionedshoulmentioned pivot pin, a lug projecting from ders engaging the opposite sides of the lug said last mentioned pivot pin, a projecting on the pin, a coiled spring having the op- 10 Web extending from said casing, a pair of 'posite ends connected with said plates, and plates loosely surrounding said pivot pin means for varying the alinement of said having overlapping projections engaging door.
